There are several settings allow you to control how and when Validatious does validation, how it displays errors and more. If configuring isn’t enough, callbacks and easy overriding gives you complete control.

You can also add custom validators with only a couple of lines of JavaScript. If your site’s language is not english, you probably don’t want error messages in english. There are several ways of changing languages as well.

PHP Security Consortium (PHPSC) is an international group of PHP experts dedicated to promoting secure programming practices within the PHP community. Members of the PHPSC seek to educate PHP developers about security through a variety of resources, including documentation, tools, and standards. You can read the PHP Security Guide they have published.

In addition to their educational efforts, the PHPSC engages in exploratory and experimental research in order to develop and promote standards of best practice for PHP application development. PHP Security Consortium has developed PHPSecInfo in order to help developers and system administrators audit PHP environments.

PHPSecInfo provides an equivalent to the phpinfo() function that reports security information about the PHP environment, and offers suggestions for improvement. It is not a replacement for secure development techniques, and does not do any kind of code or app auditing, but can be a useful tool in a multilayered security approach.

HashMask is a jQuery plugin that will produce a unique and non reversible visualization of a users password. The hope being that they would be able to confirm that they entered their password correctly, but no one else would. It also degrades gracefully so that users without javascript or a poor browser (IE6) will just see a password field.

Technically speaking, it uses a subset of the sha1 hash of the password as the seed for the sparkline’s shape and color. It should be relatively safe from reverse engineering as a result. There is the potential to estimate a possible range of characters of the first section of the hash, but overall this should be a extremely low risk.

QuickFlip 2 is now even easier to implement. The new script pulls in and applies the necessary styling, so there is no need to include a QuickFlip stylesheet or to define the dimensions of the panel you’re flipping.

Additionally, QuickFlip 2 makes triggering the flip effect much simpler due to a new flip function that can be attached to any jQuery selector. Finally, the QuickFlip plugin has been performance-tuned and is running pretty quickly.

Requirements: jQuery Framework

To facilitate this, Protovis supports panels and inheritance. A panel is a container for marks; the contained marks are replicated for each data point on the panel. You can vary the panel position to create small multiple displays, or you can overlay panels. Inheritance lets you derive new marks from existing ones, while sharing some or all of the same properties. This is the same principle as cascading in CSS, or prototypal inheritance in JavaScript.

Please note: Protovis is in its early stages of development. At the moment, they only support Firefox 3, but they plan on adding support for Chrome and Safari 4.

Requirements: Firefox 3
